“…Cheng et al [2] and Buterbough et al [7] concluded that paratracheal air cysts are more common in females than males. They demonstrated a significant association between paratracheal air cysts and sex; however, in our study, we demonstrated that tracheal and bronchial diverticula were more common in males (64%) than females (36%).…”

“…Although the etiology and pathophysiology of the paratracheal air cysts are still unknown, they are mostly considered as tracheal DV [2]. Tracheal DV is usually incidental, and the incidence is 1% in postmortem studies.…”

“…Because of the high reported incidence of tracheal and bronchial DV association with the COPD, observed hyperaeration was also noted in each DV patient. Parenchymal attenuation values below -950 HU were accepted as hyperaeration [2].…”

Objective: Tracheal diverticulum (DV) is an incidental finding in thoracic computed tomography examinations. Tracheal DV may be associated with chronic cough and chronic obstructive pulmonary disease (COPD). A few studies have investigated the relationship between tracheal DV and COPD. There is still no consensus on the relationship. The purpose of this study was to determine the incidence of tracheal DV and its coexistence with bronchial DV and hyperaeration. Materials and Methods:For the study, 299 patients from a total number of 12 800 patients who underwent a thoracic computed tomography examination were included. Tracheal diverticula were evaluated for localization, size, contour, wall thickness and communication with the tracheal lumen. The association of tracheal DV with bronchial DV and hyperaeration was also noted. The relationship between tracheal DV and hyperaeration was analyzed. Results:Of the 299 patients, a total of 412 tracheal diverticula were observed. Out of these, 148 of the tracheal diverticula were in females, and 264 of the tracheal diverticula were in male patients. The incidence of tracheal DV was determined to be 2.38% in this study. In total, 400 of the tracheal diverticula (97.1%) were located at the right posterolateral aspect of the trachea, and 320 of the tracheal diverticula were associated with hyperaeration. There was no significant relation between the tracheal DV and hyperaeration. However, 84 of 412 tracheal diverticula had a bronchial DV, and 72 of 84 of these bronchial DV were associated with COPD. Statistical analysis indicated a significant correlation with COPD and bronchial DV (p<0.05). Conclusion:Tracheal DV is often asymptomatic and mostly located in the right posterolateral aspect of the trachea. Tracheal DV is more common in men than in women. The incidence of tracheal DV was 2.38% in this study. Our data demonstrate that there was no significant association between tracheal DV and COPD. However, there was a significant association between subcarinal bronchial DV and COPD.Key Words: Bronchi, Chronic Obstructive Pulmonary Disease, computed tomography, diverticula, trachea ÖzetAmaç: Trakeal divertiküller, toraks bilgisayarlı tomografi incelemesinde insidental olarak saptanır. Kronik öksürük ya da kronik obstrüktif akciğer hastalıkları ile birlikte görülebilir. Literatürde trakeal divertikül ve kronik obstrüktif akciğer hastalıkları arasındaki ilişkiyi araştı-ran az sayıda çalışma olmakla birlikte çalışmalar arasında hala çelişki bulunmaktadır. Bizim bu çalışma ile amacımız trakeal divertiküllerin insidansını ve trakeal divertikülün, bronşial divertikül ve havalanma fazlalığı ile ilişkisini araştırmaktır. Gereç ve Yöntem:Kasım 2009-2011 tarihleri arasında toplamda 12 800 hastaya toraks bilgisayarlı tomografisi yapıldı ve çalışmaya sadece 299 olgu dahil edildi. Trakeal divertiküllerin lokalizasyonu, boyutu, konturu, duvar kalınlığı ve trakea lümeni ile ilişkisi değerlendirildi. Ayrıca bronşial divertikül ve havalanma fazlalığı ile ilişkisi araştırıldı.

“…The reported prevalence of PTACs ranges from 0.75% to 8.1% (4,(6)(7)(8). There have been a limited number of studies reporting the incidence of PTACs related to COPD or emphysema as detected by CT, and the reported results are variable (4,6,(8)(9)(10)(11). The relationship between PTACs and pulmonary emphysema or bronchiectasis is still unclear.…”

“…The best diagnostic procedures are endoscopic examination and computed tomography (1). Trauma, infection, high pressure injuries, long lasting tracheostomy, and obstructive tracheal disease are the proposed etiologies and these cysts can cause a variety of chronic and recurrent aerodigestive tract symptoms (2).…”
